A research group from the Institute of Process Engineering (IPE), Chinese Academy of Sciences, recently reported the development of a new technology to boost performance of direct methanol fuel cells (DMFCs) using high-concentration methanol as fuel, shedding some light on the design of clean and affordable alternative energy sources for portable electric devices.
When methanol, the fuel of DMFCs, crosses over from the anode to the cathode through the proton exchange membrane (PEM), fuel cell performance is significantly degraded, creating a major problem for the commercialization of DMFCs...
